FreeBSD has enhanced the nsswitch code (which is derived from our
version) to be reentrant and support dynamic loading of back-end
modules.
I have been in communication with Jacques Vidrine <nectar at FreeBSD>
(who made the enhancements) about this exact issue, as recently as
"last night at the bar at BSDcon".
When time permits, I intend to integrate his enhancements, whilst
ensuring that we maintain API and preferably ABI compatibility.

Yes, that is not correct. It's also for username, group, and shells
lookup, and is flexible enough to support arbitrary other databases
such as "printcap", "automount maps", etc and arbitrary sources
such as "mysql" or "ldap".
